Description

In the management of idiopathic trigeminal neuralgia of the second division, when the result of an infraorbital nerve alcohol block is unsatisfactory, a maxillary nerve block or the Gasserian ganglion block is performed. In both of these techniques, severe complications might occur. We experienced two cases of trigeminal neuralgia in which a greater palatine nerve block was effective.<br>A 79-year-old woman and a 66-year-old man, presented with trigeminal neuralgia of the second division. An infraorbital nerve alcohol block was unsuccessful in relieving pain in both cases. Therefore, a greater palatine nerve block was performed intraorally, which produced satisfactory results.<br>A greater palatine nerve block through the intraoral route has the following advantages technically the procedure is easily performed, there is less risk of severe complications, and the area of numbness is limited. When an infraorbital nerve block is unsatisfactory, a greater palatine nerve block should be applied prior to the maxillary block or the Gasserian ganglion block.
